To all 'whom t may cou/cem.' under the control of the engineer by mean's Be it known that l. human A. KEITH, a lof the pressure regulating valve 4l (see Fig. 5 citizen of the United States. residing at Los l.) in the cab of the engine. This valve may Angeles, in the county of Los Angeles and be of such Character :as to indicate to the. 5.State of California. have. invented new and engineer any failure to use the lubricant at useful Improvements in Lubricating Systhe proper places and in proper quantities, tenis, of which the following is a speciiicaso v'that the excuse that the device is not 60 tion.` y lvvorkinpr properly Will not be available. The My invention relates more particularly to air pipe 13 extends downwardly and commeans to properly lubricate the flanges on municates with the spray valve l5. There the wheels of railway rolling stock and the beinga spray valve on eaehside of the rails on. which they7 travel. r truck to properly spray the head of each 65 It is one of the objects of my invention rail and the flange of each Wheel thereon, to provide an apparatus easily accessible to and to that end l have connectedv this air y. l5 the engineer and Aunder his control, for supply pipe` 13 with the horizontally disproperly lul'irieating the wheel anges andv posed pipe 39 which connects at each end the rails on the curves in the track wlierewith a spray valve l5 having a spray nozzle 70 ever required. A 24. This is more particularly shown in Fig. The invention consists iii a lubricant supi '7. The .downwardly extending oil supply plying medium, exposed to air pressure-, pipe 17 is also connected with horizontally which conducts the lubricant to a distrilmt- .disposed pipe which also. terminates at ingr nozzle Whore it is atom ized and forcibly each; end iin the spray valves. Disposed on 75 discharged upon the' wheel flange and rail, the oil supply pipe 17 intermediate the oil to thereby reduce friction and Wear. tank and the spray valve is the strainer 16 My invention is shown in the accompany-A shoivn' in enlarged detail in Fig. When pressure is puton, the air in the air pipe Figure 1 is an elevation, of n locomotive .will cause the oil inthe oil tank to flow 80 engine with my lubricating .systei'i'i in place `down through the pipe 17 into the spray I thereon.

sure is maintained in the tank, and the supl ply of lubricant fedl therefrom is always mounted on the front end ot the locomotive tender, connected with the spraying mechanism and adapted to project a spray of atomized oil on the ange of the wheel and the head of the rail 23, Fig. 7, the spray nozzle 24 being prolonged'downwardly so as to discharge the ,spray atl the proper position to oil the flange and the rail. The oil tank located'on the tender, is connected with the spray valve and the air supply in manner similar to that on the locomotive already described, except that the Aconnections on the tank have flexible hose unions 24 to permit a lateral movement ofthe spray nozzles relative to the frame of the truck as the truck is passing over curves in the track. This lateral movement of the spray nozzles rela- `tive to the truck is accomplished by the adjusting bar 26, which has an intermittent longitudinal movement on the frame 2T. At

each end of the bar 26 a bolt 28 projects downwardly through longitudinal slots Q9 therein and lhas a scrcwthreaded engagement in the frame 27, thereby permitting the adjusting bar to have the aforesaid longitudinal movement on the frame 27. To hold the bar in its normal adjusted position on the frame, coiled springs are connected j atone end by the bolts 28to the frame and at the other end are securedby the bolts 3l 'i so to the adjusting bar. This adjusting bar is provided with recesses B2 for the. reception of the flanges 33 on the wheels, so that it is kept at all Vtimes in the same point with reference to the flanges on the wheels. In

.ing curves, but means are herein provided to lkeep the discharge nozzle of each spray valve in-its proper positionwith reference to the vflange of the wheel and the head of the rail, so that the atomized oil ejected in the form of a spray from the nozzle will always spray thev flange and the-'rail follows. A. pin 311- is rigidly secured to the bot- 'tom of thc frame and projects downwardly beyond an adjusting rod 35, which has an offset portionBG which partly surrounds the downwardly projecting pin 34 at thisI pol'nt, so that said rod .will be movedl longitudinally, by virtue of its connection with the xed downwardly projecting pin, as the truck swings. The adjusting rodv 35 is pivotally connectedl at both of its ends, as at 37, with projecting arms 38 rigidly secured to the nozzles 24 of the sprayvalves, so that the nozzles will be rotated slightly when the adjusting' rod moves, and the discharge nozzles always will be kept 'close to the flanges?i Lacasse mitting' this limited movement. j
